CBS Responds to Pauley Perrette's Claim That She Left 'NCIS' After 'Physical Assaults'

CBS has responded to Pauley Perrette‘s claim that she left NCIS after “multiple physical assaults.”

In a statement obtained by PEOPLE on Tuesday, CBS Television Studios confirmed that the actress came forward with a “workplace concern” over a year ago and that it “took the matter seriously.”

“Pauley Perrette had a terrific run on NCIS and we are all going to miss her,” CBS Television Studios said in the statement.

“Over a year ago, Pauley came to us with a workplace concern,” the statement continued. “We took the matter seriously and worked with her to find a resolution.”

The statement concluded: “We are committed to a safe work environment on all our shows.”

On Tuesday evening, Perrette thanked CBS on Twitter for its support: “I want to thank my studio and network CBS They have always been so good to me and always had my back.”

Days after her emotional May 8 finale, Perrette, who starred as Abby Sciuto for 15 seasons, spoke out about her recent departure from the CBS drama on Twitter.

“I refused to go low, that’s why I’ve never told publicly what happened. But there are tabloid articles out there that are telling total lies about me. If you believe them? Please leave me alone. You clearly don’t know me. (Sorry guys, had to be said),” Perrette, 49, tweeted Saturday.

A day later, Perrette posted three more tweets, in which she claimed a “machine” is “keeping me silent” and alleged that there were “multiple physical assaults.”

“Maybe I’m wrong for not ‘spilling the beans’ Telling the story, THE TRUTH. I feel I have to protect my crew, jobs and so many people. But at what cost? I.don’t know. Just know, I’m trying to do the right thing, but maybe silence isn’t the right thing about crime. I’m… Just… ?” she tweeted Sunday.

“There is a ‘machine’ keeping me silent, and feeding FALSE stories about me. A very rich, very powerful publicity ‘machine’. No morals, no obligation to truth, and I’m just left here, reading the lies, trying to protect my crew. Trying to remain calm. He did it,” she continued.

She concluded in another tweet: “I’ve been supporting ant-bullying programs forever. But now I KNOW because it was ME! If it’s school or work, that you’re required to go to? It’s horrifying. I left. Multiple Physical Assaults. I REALLY get it now. Stay safe. Nothing is worth your safety. Tell someone.”

After her goodbye episode, the actress didn’t go without thanking her fans for all of their support throughout the years in a video message shared to NCIS‘ Twitter page.

“I hope that the fans will remember everything that Abby has taught all of us over the course of this entire run,” said Perrette. “I have learned from my fans just such an incredible love and support. Abby fans are incredible, they really are the best. I can’t imagine a fan group being any better than that.”

She continued, “They really make me smile. My fans are funny and they’re smart and they’re kind and they’re caring and they’ve been so supportive. Not only of Abby, on the show, but of me, of Pauley. I love them. I’m proud of the group of fans that Abby has attracted because it’s a pretty amazing group of people.”

At the end of the video, Perrette addresses her fans directly, “To all the fans around the world, I want to tell you, with all of my heart, how much I love you guys. How grateful I am, for all of your support of both Abby and me over all of these years. And just to remember, with me, everything that Abby’s given to us. And everything she’s taught us. I cannot thank you enough. I am so blessed to have fans like you and it means everything to me. Thank you.”
